Description:

A rotating reference frame can be studies from inside
the frame (on the merry go round) or outside (watching the merry go round).
To the people inside the frame, a thrown tennis ball appears to deviate
from a straight line trajectory. To the people outside the frame, the
ball travels a straight line.
